The city of Venice and software developer Diego Pizzocaro have announced a free smartphone app titled "hi!tide Venice." The app is available in English for both iOS (iPhone) and Android, and it predicts acqua alta (tidal flooding) with data supplied by Venice's official tidal-monitoring and flood-warning service, the Istituzione Centro Previsioni e Segnalazioni Maree.
The app's main screen shows the current tide plus anticipated low and high tides over the next two days. You can click on a daily forecast for a more detailed view that includes an hour-by-hour graph.
You'll also see icons for "Places" and "Ferries" that show current tide levels at main points of interest (such as the Piazza San Marco) and vaporetto piers.
